I have two left I need help with and dont understand. Find the partial sum S6 1. An=3n+2 2. Find the number of terms n in an arithmetic sequence if a1=20, d=5, and An=75.
Thanks for the help bobpursley and Reiny I appreciate showing how you got to it so I can also do it.
I have 3 questions I'm stuck on and would love for someone to explain and show me how to solve them so I can also solve the other one. Find the partial sum S6 1. An=3n+2 2. Find the number of terms n in an arithmetic sequence if a1=20, d=5, and An=75. 3. Find the general t...
I have a few problems I need some help with. The first is Evaluate the sum. 1. There is an E like symbol on the top is 10 on the bottom n=1 and to the right (7-2n) 2. The next question is find a10 for an arithmetic sequence with a1=6 and d=10 3. Find the number of terms in the...
